Inventor: DIETZE WERNER
IPC: C12M1/40
Filed: 1991-07-15
Abstract: Electrochemical analysis system, which comprises disposable analysis elements (10) and an evaluation device (20). The analysis elements (10), in a sample infeed area (12), have a working electrode (13) and a reference electrode (14). In a terminal area (19) there are terminal contacts (17) which are connected to the electrodes via connection lines (16). The evaluation device has an analysis element terminal with appliance contacts (21) for the electric connection to the terminal contacts of the analysis elements. 
<??>Improved reliability and accuracy of the analysis with relatively little effort is achieved in that the measurement and evaluation circuit (23) has a switchover device (51), via which an electric voltage source (45) having a current-measuring device (52, 43, 49) and a voltage-measuring device (41, 39) can optionally be connected to various terminal contacts (17a-17d) of the analysis element (10).

Patent DE-4133541-A1 (DE)
Inventor: GERDES KNUD DR
IPC: E04B1/76
Filed: 1991-10-10
Abstract: Fibres used for insulation and absorption purposes can be optimally processed in a dust-free manner by mixing the absorption/insulation material shortly before leaving the injection hose or the spray gun with a special foam and then discharging it as a common mass. In this case, the foam can be produced as such beforehand from water, air and a special foaming agent or from binding agent, if necessary with water and air, with or without the addition of foaming agent, and then added to the fibre material and mixed with this. It is however also possible to combine the production process of the foam with the mixing with the fibres or to influence the foam by adding air. The injection hose (3) and the spray gun (7) have, at the outlet, a double tube (8), into which the foam tube (6) leads and whose inner tube (13) is equipped with sluices (10, 11), it being possible for the outer tube (9) to have bores (14, 15) for supplying air. <IMAGE>

Title: Lighting assembly for operating theatre - has central light source and auxiliary reflector in addition to main reflector for capturing light which escapes main reflector.
IPC: F21V9/04
Filed: 1991-12-06
Abstract: The lighting assembly for an operating theatre includes a housing (11) with a lower illumination aperture (12) and a central light source (13) supplying all-round light to a circular concave main reflector (14) which returns the incident light through the aperture (12) such as to concentrate in the operating area (15). An auxiliary circular and concentric reflector (17, 18) collects light which would normally escape the main reflector (14) and returns the light to the diametrically opposite surfaces of the main reflector (14) for additive reflections to the operating area (15). A translucent screen (25) diffuses the conical light beam and orientation is adjustable via the stem (27). USE/ADVANTAGE - Increases efficiency by capturing light which would otherwise escape reflection. Steep sided hollow cone of light eliminates shadows from objects within cone, e.g. surgeons upper body. Near vertical orientation of concentrated beam illuminates deep surgical incisions with minimal shadow and good colour rendering.

Title: Multiple substrate holder e.g. for cathodic sputtering unit - provides identical masking and identical motion of substrates
Inventor: BODEN THOMAS DIPL ING
IPC: C23C14/50
Filed: 1992-09-16
Abstract: Appts. is for simultaneously holding several substrates, with a slender circular cylindrical configuration and located in an evacuated coating chamber, e.g. a cathodic sputtering unit for uniformly partially coating the visible surfaces of the substrates. The chamber contains one or more storage arms or storage plates which can be coupled to a motor-driven shaft for rotation and which extend in a plane transvers to the rotational axis of the shaft. The storage plates have, in the region of their arcuate outer edges adjacent rotatably mounted friction rollers which cooperate with stationary track shoes and which roll on these track shoes when the storage plates rotate. A holder tube, for accommodating a substrate, is fixed to each friction axis of the driven shaft. ADVANTAGE - The appts. allows rapid mounting of substrates of complex three-dimensional configuration onto the substrate holder so that they are all identically covered by a mask for partial coating and are moved in an identical manner within the chamber. The appts. has a size suitable for incorporation in any conventional cathodic sputtering unit without any significant modification of the unit.

Patent DE-4312396-A1 (DE)
Title: Catalytically active additives for the liquid-phase pyrolysis of hydrocarbons
Inventor: HUETTINGER KLAUS J PROF DR
IPC: C10G11/02
Filed: 1993-04-16
Abstract: Catalytically active additives are described for accelerating and controlling the liquid-phase pyrolysis of industrial hydrocarbon mixtures. The additives are organometallic compounds in the broadest sense which are completely soluble in liquid industrial hydrocarbon mixtures and which decompose in the course of the liquid-phase pyrolysis in the temperature range from 350 to about 500 DEG C, possibly even earlier, the catalytically active component, the metal or possibly an inorganic metal compound such as an oxide or sulphide being released. In addition to the acceleration of the reaction of the liquid-phase pyrolysis which makes possible a temperature reduction or a decrease in reaction time, the additives or the active components released therefrom have different positive side-effects, such as influencing the nucleation in the formation of the polyaromatics mesophase which proceeds in the advanced stage of the pyrolysis, or else an increase in the coke yield. However, a particular advantage is the binding of the organically bound sulphur of the industrial hydrocarbon mixtures, in the case of organoiron compounds, e.g., with formation of iron sulphide. The catalytically active additives are suitable both as additives to binder pitches or else impregnation pitches and for the modification of pitches or for the synthesis of polyaromatics mesophases and cokes.
